Production

KADOKAWA announced the project as a new anime featuring Gamera, with worldwide distribution on Netflix.² The series was produced by studio ENGI as a 3DCG anime, directed by Hiroyuki Seshita with Keisuke Ide as co-director.²^•¹ In an interview, Seshita said that when Kadokawa offered him the project, he accepted on the condition that it be not just hard science fiction but a pure, pro-wrestling-style combat anime, and that bringing the older characters of the Gamera franchise into a new era was a main goal.⁹

The main voice cast was announced as Hisako Kanemoto as Boko, Yoshitsugu Matsuoka as Joe, Aki Toyosaki as Junichi, and Subaru Kimura as Brody, with Mamoru Miyano and Saori Hayami among the additional cast.⁵^•² An exclusive edit of the first episode and a second trailer premiered at San Diego Comic-Con 2023, where Viras was revealed as the fifth kaiju and the main theme "Natsuake" by WANIMA was showcased.¹

Place in the Gamera franchise

Gamera debuted in Gamera: The Giant Monster, a special-effects film released in 1965 by Daiei Film, now part of Kadokawa. The character is portrayed as a protector of humanity, a friend to children, and an ally of justice, with a humorous turtle-like design and the ability to fly, including spinning like a disc, and to breathe fire.² Eight Gamera films were produced from the 1960s through the 1980s, followed by a three-part Heisei series in the 1990s (Gamera: Guardian of the Universe in 1995, Gamera 2: Attack of Legion in 1996, and Gamera 3: Revenge of Iris in 1999) and the 2006 film Gamera the Brave.²^•¹⁰

Rebirth arrived seventeen years after the monster's last film and was the first Gamera-focused television series.⁸ Kadokawa positioned it as the first Gamera work of the Reiwa era, following the Showa and Heisei generations.¹⁰

Release and related media

All six episodes began streaming on Netflix worldwide on September 7, 2023.¹ A re-edited television version began broadcasting on NHK General on Saturdays at 23:45 from April 2025, and a Blu-ray BOX was released on March 25, 2026, coinciding with the 60th anniversary of the Gamera franchise, which a limited merchandise project also marked.¹¹

A vertical-scrolling, full-color manga adaptation illustrated by Renga Kizima began serialization on Kadokawa's KadoComi service on September 13, 2023, with English translations sold through BOOK☆WALKER. After the 15th chapter was released on January 27, 2025, completing the adaptation of the series' second episode, all but the first three chapters were removed from KadoComi and the manga went on indefinite hiatus.¹² A prequel comic, GAMERA -REBIRTH-: CODE THYRSOS, was announced by Titan Comics.¹³

Reception

Starburst's review called the series a deeply impressive return, praising the balance between action and emotional weight and noting that the motion-smoothed animation served the kaiju battles better than the human characters.⁸ Audience ratings varied by platform: TMDB listed 7.8, JustWatch 6.6, and the Japanese review site Filmarks averaged 3.5 out of 5 from 835 user reviews.¹⁴^•⁶^•¹⁵ Some viewers criticized the 3D character animation while praising the monster fights.¹⁴

Director Seshita said during the press tour that a second season would be produced if the show performed well, and that Kadokawa had also considered a live-action Gamera series under the same condition. According to one kaiju-industry tracker, Netflix numbers released afterward indicated weak performance, making a second season unlikely, though nothing has been formally announced either way.¹⁶
